98% of the time this condition occurs the fertilized egg is spontaneously
aborted long before a baby can come to term

Are any human traitsdetermined by a single gene?
Traits that are determined by theinstructions a person carries at onegene are called single-gene traits.
9,000 human traits

Mendel f igured out t he rules of genetics byworking wit h pea plant s. Why were t hese
plant s a good t ool for Mendel t o use t oanswer his questions about inherit ance?
1. Individual plant s could be self-fertilized orcross-fertilized wit h ot her individuals.
2. They grew quickly (short generation time).
3. Clearly def ined t rait s (yellow vs. green) were
observed.
4. A ll of t he above.

Three Ideas Mendel Used for ExplainingThis Patt ern of Inherit ance
1) Each parent put s int o every sperm or egg it makes a single set of inst ructions forbuilding t he t rait .
2) Offspring t hus f ind t hemselves wit h t wocopies of t he inst ructions for any t rait (called alleles).
3) The act ual t rait produced by an individual
depends on t he t wo copies of t he gene t hat t hey inherit from t heir parent s.

The out ward appearance of an individual is called t heir phenotype.
Underlying t he phenot ype is t hegenotype.
This is an organisms genetic composition.

How do we analyze and predict t heout come of crosses?
A ssign symbols t o represent t he different variant s of a gene.
Generally we use an uppercase lett er for t hedominant allele and lowercase for t herecessive allele.
If we dont know which of the two possible
genotypes the pigmented individual is, we canwrite A _, where the _ is a placeholder for theunknown second allele, whose identity we arentcertain of.
